Vibration-assisted machining (VAM) is an external energy-assisted machining method in which high frequency and small amplitude vibration is superimposed to the tool or workpiece to improve the material removal process. It has been applied to a number of cutting processes from turning, drilling, grinding, to milling. This chapter attempts to introduce the vibration-assisted milling. Firstly, generic kinematic equations of vibration-assisted milling are formulated, then three types of tool–workpiece separation (TWS) mechanism are proposed and the requirements to realize each type of TWS are discussed through kinematic analysis and simulation. Secondly, the state-of-the-art of the principle and structural design of VAM systems are reviewed. Finally, a case study on development of a vibration-assisted milling system and its application on machining of Ti6Al4V are presented.
